Looking for a website that gives comparative performance of diodes (max
frequency for UHF use)

I don't know of a broad-spectrum site (i.e. one which is multivendor)
other than general datasheet-search sites such as datasheetarchive.com

One good place to start looking would be atwww.avagotech.com- I
believe that Avago Technologies is the current inheritor of the line
of RF Schottky diodes originally made by HP and then by Agilent. Some
of these parts are useful up to quite a few GHz.

Yes, that is correct about Avago. I believe I've come across diodes
there rated for use up to 40GHz, maybe 65GHz.

Also, look at other web sites (of companies with "new" names also!)
NXP used to be Philips. They definitely have some good RF detector
diodes. A Google search on "RF detector diode" just now turned up
several interesting hits, including some for sale on ebay. I saw
Vishay listed as an RF detector diode supplier, too, and I wasn't
aware they were really into that area--looks like they acquired
Telefunken, for another name change! But I suppose Suzy is looking
for non-surface-mount parts (from postings in another thread), and
that likely will be a problem for any new stuff. Pretty much
everything now has gone to tiny surface mount packages. -- OK, I
have to take that back. The Vishay web site has a kind of neat
feature and lets you look by package type--click on the picture of the
package. And it's real pictures, not line drawings. They DO have
glass axial lead RF diodes.
